I have found this extract:
Every Sunday afternoon, the labourers at Mr. Wilder's lime-kiln were in
the habit of visiting a small public-house, at the hamlet of Tickencote,
called 'the Flower Pot.' Thirsty, like all of their tribe, they spent
hours in carousing; while John Clare, after having had his glass or two,
went into the fields, and, sitting by a hedge, or lying down under a
tree, surveyed the glories of nature, feasting his eyes upon the
thousandfold beauties of earth and sky. It was on one of these Sunday
afternoons, in the autumn of 1817--Clare now past twenty-four--that he
saw for the first time 'Patty,' his future wife. She was walking on a
footpath across the fields, while he was lying in the grass not far off,
dreaming worlds of beauty and ethereal bliss.
